Title: Method for monitoring data network
Inventor: D SOUZA KEVIN L
IPC: H04L12/26
Filed: 2000-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a method for accurately monitoring the availability of a data network independently of the size of the data network. SOLUTION: The availability of a connectionless network 10 is discriminated first by identifying all possible data destinations. In other words, all possible network end points are first discriminated. Then routing tables 36, 38, 40 in routers 18, 20, 22 are checked to discriminate whether a route to each end point is in existence. Then the number of available routes to each end point and the number of the end points are compared to evaluate the availability of the network. If a route reaching all the end points is present, the network 10 is completely available and the absence of a route to an end point decreases the availability of the network.
